Abstract
The utility model relates to an anti-freezing water supply pipe. The pipe wall of the anti-freezing water supply pipe is composed of two layers, namely an inner layer and an outer layer, the inner layer is made of materials with the certain compression ratio amplitude, and the inner layer is tightly matched with the outer layer. An inner pipe is made of a pneumatic membrane or soft rubber. The space which is compressed after the inner pipe is stressed can compensate the space which is needed when the size of water in the water supply pipe in a frozen state is enlarged, and therefore the anti-freezing effect is achieved.
Description
Technical field
The utility model relates to a kind of antifreeze supply pipe.
Background technique
At present, advantage such as synthetic plastic PPP pipe is people's daily life supply pipe, and its non-corrosive is easy for installation, and cost is low has substituted the steel pipe supply pipe.But in the severe cold time, there's a sudden fall in temperature, and behind the water freezing, volume becomes the supply pipe that will rise brokenly greatly, has shortcomings such as not antifreeze in the pipe.
The model utility content
The purpose of this utility model is to overcome the existing not antifreeze defective of supply pipe, and a kind of antifreeze supply pipe is provided.
The technical solution of the utility model is: antifreeze supply pipe tube wall is made of two-layer, i.e. internal layer and skin, and internal layer is for having certain compression ratio amplitude material, and internal layer and skin closely cooperate.
The interior water of supply pipe is solved under the state of freezing in compressed space, the stressed back of pipe in the antifreeze supply pipe utilization of the present utility model, and volume becomes big needed space, thereby reaches antifreeze effect.
Description of drawings
Fig. 1 is antifreeze supply pipe of the present utility model structural representation under water state.
Fig. 2 is antifreeze supply pipe of the present utility model structural representation under the ice state.
Among the figure: pipe in the 1-, 2-outer tube, pipe water state radius in the c-supply pipe water state cross section, r-supply pipe, tube thickness in the h-water state, c
1-supply pipe ice state cross section, r
1-Nei pipe ice state radius, h
1-Nei manages compressed thickness.
Embodiment
Antifreeze supply pipe tube wall is made of two-layer, i.e. internal layer 1 and outer 2, and internal layer is for having certain compression ratio amplitude material, and as aerated film or software rubber etc., internal layer and skin closely cooperate.
Its principle is: the water of homogenous quantities is under the state that freezes, and its volume can become greatly, and Here it is causes the not antifreeze reason of general supply pipe, according to physical equation: and P(density)=m (quality)/v (volume) can derive the volume ratio I behind the water freezing; I (frozen water volume ratio)=v(ice)/v (water), but formulation is derived the water freezing front and back, the data that pipe changes in installing additional, thus produce antifreeze supply pipe.Fig. 1 is supply pipe under the water state, c=π r
2, c is supply pipe water state cross section; π is Ratio of the circumference of a circle to its diameter; R is pipe water state radius in the supply pipe; Fig. 2 is supply pipe under the ice state, c
1=π r
2I, c
1Be supply pipe ice state cross section; π is Ratio of the circumference of a circle to its diameter; R is that supply pipe water state radius: I is ice and water volume ratio, is about 1.09.Volume Changes makes r increase to r behind the water freezing
1H is the interior pipe thickness of pipe, h
1Be interior pipe compressed thickness; h
2Be the compressed thickness of interior pipe; r
2=h-h
1; Because of r
1-r=r
2, r
2For volume behind the water freezing becomes the radius that big back increases, the compressed thickness of interior pipe that just installs additional, i.e. r
2=h
2, selecting the compression ratio of material for use as interior pipe is I
1, I
1=h
2/ h, h
2=I
1H; According to above-mentioned principle and the theoretical total data that can draw the antifreeze supply pipe of production.
Claims (2)
1. an antifreeze supply pipe is characterized in that antifreeze supply pipe tube wall is made of two-layer, i.e. internal layer and skin, and internal layer is for having certain compression ratio amplitude material, and internal layer and skin closely cooperate.
2. antifreeze supply pipe according to claim 1 is characterized in that described internal layer is aerated film or software rubber.
